Hi Chris, Yes, any slop in the guide assembly, e.g. mounting, camera, focuser, etc., can lead to differential flexure and it can be a real pain to isolate and fix. You mentioned that it appears in the

It sounds like differential flexure to me. Have you check that the guide scope hasn’t worked loose from the main OTA, it won’t need much and you probably won’t even see it. Guide performance may well

Hi Mikey, I don't use either APCC or Stellarium to control my AP1200, but I achieve what you are trying to do by setting a meridian delay in the V2 driver, so have you tried that? I'm not on my observ

Don, Thanks for pointing out my error, I should have read the original post. Yes, a 12" will make the difficulties that I experienced with my 10" Meade all the more challenging, but I believe that it

Hi Dick, I tend to agree with most of the advice you've been getting, BUT I want to say that it is not so difficult to get images with a 10" Meade LX200 and a stock DSLR (mine was the Nikon D90) as th

Thanks Ray, I've sent you a private email to your groups3 address. Regards, Geof

#APCC

Hi Ray, I don't own APCC, I just use the V2 driver. To be more accurate in my description of the problem, it is true that the V2 driver continues to allow me to park with CW up, BUT since August last

#APCC

I also use SGP and have a flat panel on the wall of my observatory. All I did was set a custom AltAz park position in the V2 driver so that the OTA points square to the flat panel when parked. Please

Hi Rick, In the V2 driver there is a check box option to ‘Use RCAL for Syncs’, so just have that box ticked. Cheers, Geof Get Outlook for iOS

Dean, Those 3 are great, thanks for sharing them. I had a look at some of your other work posted on AB - all very good. FWIW I'm using a 2007 vintage AP1200GTO CP3 and it rocks - but then it's like a

John, I don't have APCC, but I do use SGP and I can set either positive or negative values in the Meridian Delay setting of the V2 driver, which SGP then uses to either advance or delay the meridian f

Hi Richard, I do this all the time with my 12 year old AP1200GTO CP3, by setting the meridian delay in the V2 driver - note I do not have APCC. A positive number moves the 'meridian' east (earlier) an

Hi, I know nothing of APPM/APPC, but I notice that you have the dark subtract checkbox checked, so do you have a dark frame to be applied to your light frame when performing plate solves. I may be way

Hi Geoff, That is an excellent image, very well processed, thanks for sharing it. I'd not heard of Burbidge's Chain previously and it really adds to the interest in the overall image. Well done reveal

Hi Claude, I achieve this by setting a meridian delay in the APV2 driver, usually no more than 2 hours, but the other night I set a +3 hour delay, which actually advances the meridian flip point east

David, That's a lovely set of images, thanks for sharing them. Geof

Ditto from me 🙂

Hi Bill and Roland, Reference to the PHD2 wiki page shows that PHD2 does not require the reverse dec output checkbox to be checked for any AP mounts. https://github.com/OpenPHDGuiding/phd2/wiki/Revers

Very nice Lee, Thanks for sharing. I did indeed have much worse weather - total cloud cover... :-( Geof

Thank Roland, My bad, I didn’t mean small refractors per se, I meant refractors smaller than my C14. Regards, Geof Get Outlook for iOS
